Below are the best books we could find on Buddha Nature.
“Buddha nature” is the English translation of several different terms within various Buddhist traditions. In contemporary Western discussions, it usually refers to the essential part of every sentient being that has the capacity to become enlightened, or develop unbiased infinite love. Some consider it to be the awakened nature that fills and is the foundation of the universe. In this perspective, we each are already a piece of this universal awakened nature, with the journey of enlightenment being a process of removing everything from our lives that inhibit our access to that nature. Discussions of Buddha nature play a large role in Buddhist discourse, and many find it a reassuring place to begin their spiritual exploration.
